Thom Yorke doesn't seem like an obvious choice for a 'Voice' mentor -- and that's why we like it. It's been a long time since Radiohead's 'Creep' was the band's biggest hit in America, and in the intervening years Yorke has become much less of a freak and a weirdo and much more of an charming British bloke known to even crack the occasional smile. Plus, his voice is hands down one of the most mesmerizing in all of rock 'n' roll.
